NXP Semiconductors MKE04Z128VQH4R

Overview

MKE04Z128VQH4R from NXP Semiconductors is a 48 MHz Arm® Cortex-M0+ microcontroller with 128 KB flash, 16 KB RAM, and industrial-grade operation from –40 to 105°C. It integrates dual 32-bit FlexTimer/PWM modules, a 12-bit SAR ADC with Stop-mode operation, two analog comparators with 6-bit DACs, and supports UART, SPI, and I²C interfaces - deployed in motor control subsystems for HVAC actuators.

For engineers reviewing the MKE04Z128VQH4R datasheet, MKE04Z128VQH4R pinout, MKE04Z128VQH4R application, or MKE04Z128VQH4R equivalent, this page delivers verified electrical specs, package mapping to 64-pin QFP, validated peripheral timing (FTM, ADC, SWD), thermal resistance data (RθJA = 61°C/W), and direct alternative part comparisons - all confirmed against NXP's KE04 Sub-Family Data Sheet Rev. 6 (04/2020).

Technical Context

The MKE04Z128VQH4R implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiply and single-cycle I/O port access. Its clock system combines an external 4–24 MHz crystal oscillator (OSC) with an internal FLL-based ICS supporting 48 MHz system clock generation from a 37.5 kHz pre-trimmed reference.

System-level features include three power modes (Run/Wait/Stop), low-voltage detection with selectable trip points (2.56–4.4 V), and hardware CRC, BIT-BAND, and BME modules. Analog integration comprises one 16-channel 12-bit SAR ADC (Stop-mode capable) and two ACMPs each with programmable reference and embedded 6-bit DAC.

FAQ

What is the maximum operating frequency of the MKE04Z128VQH4R?

The MKE04Z128VQH4R operates at a maximum core frequency of 48 MHz, achieved via its internal FLL locked to either an external 4–24 MHz crystal or the factory-trimmed 37.5 kHz internal reference. Bus clock runs at half-core frequency (24 MHz), and all timing-critical peripherals - including FTM modules and ADC conversion - are synchronized to this bus clock. This frequency is fully characterized across –40 to 105°C and 2.7–5.5 V supply range per NXP KE04 Sub-Family Data Sheet Rev. 6.

Does the MKE04Z128VQH4R support debug interfaces, and what are the requirements?

Yes, the MKE04Z128VQH4R supports Serial Wire Debug (SWD) via dedicated SWD_DIO and SWD_CLK pins. SWD_CLK operates up to 24 MHz with guaranteed timing margins: setup time ≥10 ns, hold time ≥3 ns, and data valid window ≤35 ns after clock rise. No external pull-up resistors are required, and the interface remains functional across the full 2.7–5.5 V supply range. The MKE04Z128VQH4R does not support JTAG; SWD is the sole debug interface.

What analog capabilities does the MKE04Z128VQH4R provide for sensor interfacing?

The MKE04Z128VQH4R integrates one 12-bit SAR ADC with up to 16 input channels, capable of operation in Stop mode with hardware trigger support - enabling precise current or voltage sampling during low-power states. It also includes two analog comparators (ACMPs), each with a programmable reference input and an embedded 6-bit DAC for threshold generation. These ACMPs support windowed comparison and interrupt generation, eliminating need for external comparator ICs in overvoltage or zero-crossing detection circuits.

How does the MKE04Z128VQH4R manage power in low-energy applications?

The MKE04Z128VQH4R implements three power modes: Run, Wait, and Stop. In Stop mode, with only the 1 kHz LPO active, supply current drops to 1.9–2 µA at 3 V. Additional peripherals - ADC, ACMP, and LVD - can be selectively enabled as "adders" to Stop mode, increasing current by 82–130 µA depending on configuration. This granular control allows designers to balance wakeup latency against energy consumption, making the MKE04Z128VQH4R suitable for battery-operated nodes with multi-year lifetime requirements.

Is the MKE04Z128VQH4R pin-compatible with other KE04 family members?

Yes, the MKE04Z128VQH4R is pin-compatible with other 64-pin QFP variants in the KE04 family, including MKE04Z64VQH4R and MKE04Z128VQH4. All share identical pin assignments, electrical characteristics, and package dimensions (14 mm × 14 mm). Firmware developed for MKE04Z64VQH4R will run unmodified on MKE04Z128VQH4R, though flash/RAM utilization must be validated. Pin compatibility is confirmed in Section 8.2 ("Device pin assignment") of the KE04 Sub-Family Data Sheet Rev. 6.
